Does my bum look big in this!

I don't usually take Jonty to church to pick up Great Granny, although she's a Great Great Granny since a couple of months ago! Sometimes though he just really wants to go with me, even if he doesn't have any idea where I'm going.
Tonight he came with me and we waited at the rear of the church, which F.M.i.L. calls the front because it's the end where the altar is.
Jonty was up on his back legs and waving his front legs in the air when he saw her coming down towards us. By the time I got the camera on my phone open he had stopped.
He is looking very white and fluffy because he was at the groomers this morning. It's the fluffiness that is making his rear end look so big, and maybe a bit of perspective.
